Assign VDI Models
As with physical desktops, it is not possible to meet every user requirement with a single type of VDI.
Different types of users need different types of resources. Some users may require simplicity and
standardization, while others may require high levels of performance and personalization.
Implementing a single VDI model across an entire organization will inevitably lead to user frustration
and reduced productivity.
Citrix offers a complete set of VDI technologies that have been combined into a single integrated
solution. Because each model has different strengths, it is important that the right model is chosen for
each user group within the organization.
The following list provides a brief explanation of each VDI model.
Hosted Apps – The hosted apps model delivers only the application interface to the user. This
approach provides a seamless way for organizations to deliver a centrally managed and hosted
application into the user’s local PC. The Hosted Apps model is often utilized when organizations
must simplify management of a few line-of-business applications. Hosted apps includes a few
variants:
Windows Apps – The Windows apps model utilizes a server-based Windows operating
system, resulting in a many users accessing a single VM model.
VM Hosted Apps – The VM hosted apps model utilizes a desktop-based Windows
operating system, resulting in a single user accessing a single VM model. This model is
often used to overcome application compatibility challenges with a multi-user operating
system, like Windows 2008, Windows 2012 and Windows 2016.
Linux Apps – The Linux apps model utilizes a server-based Linux operating system,
resulting in a many users accessing a single VM model.
Browser Apps – The browser apps model utilizes a server-based Windows operating
system to deliver an app as a tab within the user’s local, preferred browser. This approach
provides a seamless way for organizations to overcome browser compatibility challenges
when users want to use their preferred browser (Internet Explorer, Microsoft Edge,
Google Chrome, Mozilla Firefox, etc.) but the web application is only compatible with a
specific browser.
Shared Desktop – With the shared desktop model, multiple user desktops are hosted from a
single, server-based operating system (Windows 2008, 2012, 2016, Red Hat, SUSE, CentOS and
Ubuntu). The shared desktop model provides a low-cost, high-density solution; however,
applications must be compatible with a multi-user server based operating system. In addition,
because multiple users share a single operating system instance, users are restricted from
performing actions that negatively impact other users, for example installing applications,
changing system settings and restarting the operating system.
Pooled Desktop – The pooled desktop model provides each user with a random, temporary
desktop operating system (Windows 7, Windows 8 and Windows 10). Because each user receives
their own instance of an operating system, overall hypervisor density is lower when compared to
the shared desktop model. However, pooled desktops remove the requirement that applications
must be multi-user aware and support server based operating systems.
Personal Desktop – The personal desktop model provides each user with a statically assigned,
customizable, persistent desktop operating system (Windows 7, Windows 8, Windows 10, Red
Hat, SUSE, CentOS and Ubuntu). Because each user receives their own instance of an operating
system, overall hypervisor density is lower when compared to the shared desktop model.
